When a refrigerant trace gas becomes absolutely necessary which of the available refrigerants should be used to identify a leak?
Oxygen
Where is the air conditioner refrigerant refill port located on a 1997 f350 powerstroke how to refill it and what are necessary precautions?
should be preformed by proffessionals only
Why is it necessary to recover refrigerant?

What refrigerant does a e34 need?
The type of refrigerant that an E 34 needs is R12 refrigerant. It is absolutely necessary that you do not put any other type of refrigerant into a R12.
Is it necessary to put freon in an central air conditioner yearly?
NO if your puting refrigerant in your system yearly that means you have a small leak some where and it needs to be found.. if your service tech says this is normal he or she needs to go to school for HVACR...
Is hair conditioner is good or not?
Yes, conditioner gives your hair necessary nutrients and vitamins to be healthy.
What were the challenges for making a refrigerator?
The largest challenge was (and still is) finding and making refrigerants that are both safe and effective. The earliest refrigerants were either highly toxic and/or highly flammable, many people died because of refrigerators using these refrigerants. With DuPont's invention of freons which are both nontoxic and nonflammable and thus seen as the ideal refrigerants, the refrigeration industry took off. But with the discovery that freons destroy the protective ozone layer of the atmosphere it has again become necessary to seek new refrigerants, most of the current options are slightly flammable!Another challenge was to develop seals for the pumps that compress the refrigerant that won't fail prematurely, allowing possibly toxic or flammable refrigerants to escape. Albert Einstein invented an electromagnetic pump with no moving parts (thus needing no seals), but the invention of "safe" freons made this unnecessary (however it later found use in liquid metal cooled nuclear reactor designs).
What is the disadvantage of a dial scale?
They are more difficult to use when charging refrigerant into a system and more calculations are necessary to determine the amount of refrigerant charged.

Will an automotive AC license such as MACS be adequate to purchase R-22 or other refrigerants?
You need to have the licenses to purchase any of the refrigerants you specify. Just the A/C Licenses is not enough. There is special training necessary to get the proper EPA permits to purchase and handle them.
Is it better to leave your air conditioning running all the time - or to switch it on and off as necessary?
Your air conditioner should have a built in thermostat and cycle as necessary. The air conditioner takes a little while to reach peak efficiency. Once the room is cooled it will cycle on and off as necessary. If you manually cycle the air conditioner, you are greatly reducing its efficiency.
